Description

Industrial fan structure with automatic steering function

The present invention is an industrial fan structure with an automatic steering function, and the technical content relates to driving the turntable to continuously deflect left and right within a fixed angle by using a driving device, so that the industrial axial flow fan mounted on the turntable can automatically swing back and forth.

The axial flow fan is a classification of a fan, meaning that the wind blown by the fan will be in the same direction as the axis of the fan impeller (ie, the flow direction of the wind and the axis are parallel), such as a household electric fan, an air conditioner external fan, and a row above the tunnel. Fans, etc. Axial fans are often used in ventilation, ventilation, heat dissipation, etc. in industrial plants, farmhouses, etc., also known as local fans. When the axial fan is in operation, the airflow enters the fan, and the air is sent through the fan impeller to obtain the kinetic energy, or the air duct is connected to the air outlet to introduce the airflow into the pipeline for transportation, or may be connected in series in the long exhaust duct. Installation, increase the wind pressure in the pipeline, can accelerate the speed of exhaust emissions.

The difference from the general open fan is that the fan impeller of the industrial axial flow fan is contained in a casing, which has the advantages of convenient installation, large air volume, good efficiency, obvious ventilation and ventilation effect, and high safety; In order to overcome the problems of vibration, noise, etc. caused by high-power operation, the fan needs to be firmly fixed on a stable flat base, and then the fan and the base are installed on the ground, the wall, or Ceiling and other places.

As a result, the axial fan of the conventional industry cannot change the direction of the fan impeller, so that the fan can only supply air in the same direction, which reduces the effect of air convection and causes inconvenience in use. In order to achieve better ventilation efficiency, it is necessary to purchase a larger number of fans and set them at different angles. In addition to increasing expenditure, the large fan volume also occupies a large area of utilization space, which increases storage costs.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and created an industrial fan structure with automatic steering function to improve the above-mentioned traditional axial flow fan can only be supplied in a fixed direction. Disadvantages.

The purpose of the present invention is to provide an industrial fan structure with an automatic steering function, which drives a turntable through a driving device, so that the turntable can be continuously deflected left and right at a fixed angle, thereby making the axial flow fixed on the turntable The fan automatically swings back and forth to improve the shortcomings of the traditional axial flow fan that can only supply air in a fixed direction, thereby reducing the cost of industrial production.

In order to achieve the above object, the present invention is an industrial fan structure having an automatic steering function, comprising: an axial flow fan having a fan bracket outside the fan-flow fan, the fan bracket being fixed on a turntable; and a driving The device is disposed at the bottom of the turntable, and includes a swinging member with a top portion coupled to the turntable, a transmission unit for driving the swinging member to swing back and forth in a fixed angle, and a spin motor for driving the transmission unit to be displaced. .

With the above configuration, when the spin motor in the driving device rotates, the transmission unit can be driven to cause the swinging member and the turntable connected thereto to swing back and forth in a fixed angle, so that the axial fan fixed on the turntable is The fixed angle is deflected to change the blowing direction, and the air is blown at positions in different directions.

The implementation of each component is further described below:

In practice, the driving device is mounted inside a casing, and the casing top mask has a perforation for the top of the swinging member to pass through the top surface of the casing.

In implementation, the bottom of the housing is provided with a plurality of legs, the plurality of legs being fixed to the ground or the wall.

In implementation, the bottom of the housing is provided with a plurality of rollers with a locking function, which is convenient for the operator to move to a suitable position and lock the positioning.

In implementation, the industrial fan structure is further provided with a control assembly for the operator to control the axial fan switch, the rotational speed, the elevation angle, and the deflection angle of the drive.

Compared with the prior art, the present invention can make the axial flow fan automatically swing back and forth in a fixed angle, and supply air to different positions, thereby improving the shortcomings of the conventional axial flow fan only in the fixed direction of the air supply, and reducing The manpower required to operate the fan has the purpose of reducing the cost of industrial production.

In the following, according to the technical means of the creation, the implementation method suitable for the creation is listed, and the description is as follows:

As shown in the first and second figures, the present invention is an industrial fan structure with an automatic steering function, including an axial flow fan 10 and a driving device 20, wherein the axial fan 10 has a fan bracket on the outer side thereof. 11. The fan bracket 11 is fixed to a turntable 12. In implementation, the axial fan 10 is pivotally connected to the fan bracket 11 and can change the elevation angle with respect to the fan bracket 11 to change the air supply range.

The driving device 20 is disposed at the bottom of the turntable 12, and includes a swinging member 21 with a top portion coupled to the turntable 12, a transmission unit 22 for driving the swinging member 21 to swing back and forth in a fixed angle, and a driving unit 22 The displacement-actuated spin motor 23. The driving device 20 is mounted inside a casing 30. The top surface of the casing 30 has a through hole 31. The top of the swinging member 21 is exposed from the through hole 31 and exposed on the surface of the casing 30, and then combined with the turntable 12. .

As shown in the third figure, when the operator activates the steering function, the spin motor 23 starts to operate in situ rotation, and one end of the transmission unit 22 is wound around the center of the spin motor 23 as a center, thereby driving the transmission. The other end of unit 22 is displaced.

The other end of the transmission unit 22 is displaced by the rotation of the spin motor 23, so that the adjacent turntable 12 can swing back and forth in a fixed angle, and the axial fan 10 fixed on the turntable 12 can be the same. In this fixed angle, the swing is oscillated back and forth to the left and right to achieve the purpose of blowing air in different directions.
